Mice infestation can be a big problem for private landlords to deal with – so who is responsible for mouse control in privately rented homes? Is it landlords or tenants? Mice are emotive. Many tenants will have mouse phobias. Many also have justifiable worries about health hazards, safety risks, spoiling of foodstuffs and bad smells. Meanwhile, mice infestations can damage buildings and fittings. For example, mice can chew through electrical wires, which can cause fires.
